Paper Abstract

In view of the problem that some relief symbols are difficult to build models in 3D topographic map, we take cliff symbol as an example to set up an illumination model of it according to the visual sensation rules under the different illumination conditions, propose a set of automatic modeling principles, educe automatic modeling formulas and introduce the automatic modeling method of cliff symbol in detail. The experiment proves that it is feasible. The study will be helpful to build the models of other similar relief symbols automatically.
